WHEEL.

Patented Mar. 18, 1913.

Application tiled August 26, 1909. Seri..t NoY 514,663.

To all whom, it may concern.'

Be it known that I, THOMAS B. J Erreur, 'a citizen of the United States,v residing at Kenosha, county o Kenosl1a, State of \Vis consin, have invented a certain new and use- Yful Improvement in lVheels, and declare the following to be a full, clear. and exact de scription ofthe same, such as will enable others skilled in the art to which it pertains to make and use the same. reference being had tothe accompanying drawings. which form a part of this specification.

In my prior application Serial No. 458,941, filed October 22, 1908, I have described a. novel form of vwheel which may readily be removed from the hub and replaced by a similar wheel incase of accident and the present invention has for its object to improve the construction described in such application.

The various features of novelty whereby my invention is characterized will hereinafter be 'pointed out with particular-ity in the claims; but, for a full understanding of my invention and of its object and advantages, reference may be had t-o the following detailed description taken in connection With the accompanying drawing, wherein:

Figure l is a sectional view showing my improved wheel assembled upon a hub: Fig. 2 is a View similar to Fig. l showing the wheel in process of removal: and Fig. 3 is a Side eievation with the hub cap removed.

Referring to the drawing, A represents an axle having a cone-shaped end a.

B is a hub detachably fitted upon the cone-shaped end of the axle and having an annular shoulder or flange The Wheel body consists of a series of radiating spokes C and a surrounding rim (not shown). AThe inner ends of the spokes are shaped so as to form a central opening c sulficiently large to receive the hub.

D is a sleeve litting snuglvY upon the hub and having an annular flange (.7 lying against one face of the spokes. the sleeve and its flange forming the usual hub llange. The hub flange is permanently secured to the wheel bcdy b v means of bolts ll passing through the spokes and through the flange (I. In order to secon the wheel body upon the hub I provide a second series of bolts F which are rigidly .secured to the shoulder or tlange 71 in any suitable manner as. for example. b v screwing them .into the flange as at f' and then riveting the ends as atA j" so as to prevent their removal. The bolts are long enough to pass entirely through the spokes and the member Each of the bolts F is provided with an enlargement f2 which is adapted to bear against the shoulder or flange Z1. These enlargements serve to aline the bolts properly and make it diilicultl for them to be bent ont of alinement. Consequentlyl` by shaping the bolts and their enlargements accurately they will be forced to assume positions perpendicular to the flange on the hub and will be held rigidly in such positions.

One of the chief advantages of wheels constructed in this manner is that an extra wheelmay be carried upon a vehicle in order that it may be substituted for one which has been damaged or whose tire has been disabled. lt is therefore desirable thatr the construction be such as to malte the operation of placing the wheel in position as simple and easy as possible. To this end l arrange within each of the openings (-1 through which the bolts F pass.l a thimble 4or bushing G. The thimbles or bushings are arranged on the side of the wheel body opposite to that on which the hub flange is located and they preferably extend only a short distance into the wheel body. The bore of the sleeves or thimbles is preferably made such as to produce a nice sliding lit upon the bolts. lt will be seen that the luishings or thimbles protect the bolt holesl against injury or distortion either through swelling of the wood of the spokes or by reason of the wheel being struck upon the side. The openings f'l are preferably made larger than the bolts so that the bolts remair out of contact with the wood. bearing only within the bushings. The thimbles are preferably provided with enlarged ends f ,f which fit snugly about the enlargements on the bolts F. A bearing is therefore obtained between the thimbles and the bolts throughout the entire lengths of the thimbles and a secure driving connection is obtained. Since the greatest driving strain comes upon the bolts at points adjacent. to the flange on the hub. the provision ot the enlargements on the bolts and on the bushings or thimbles insures great rigidity and consequently .small danger of distortion since it is almost impossible to bend the bolts where they enter the flange on the lu:Y by reason of the engagement ofv 'tvhe .enlargements on;` 'the bolts with 'the l'a-ngeffin-the plane 'afi-ight anglesA toglthe" bolts, namely Qin" the-[plane along the 'pressure 'during driving is dir'eictedf I is a screw-'threaded-std which passes 4through the'u-y-Ok-e andfisad'aptedfto bear at'. onefendfagainst the end ofthe aide.
